   3 # generate a .def file
   4 #
   5 # It does this by parsing the header files and looking for the
   6 # prototyped functions: it then prunes the output.
   7 #
   8 # Intermediary files are created, call libeay.num and ssleay.num,
   9 # The format of these files is:
  10 #
  11 #       routine-name    nnnn    vers    info
  12 #
  13 # The "nnnn" and "vers" fields are the numeric id and version for the symbol
  14 # respectively. The "info" part is actually a colon-separated string of fields
  15 # with the following meaning:
  16 #
  17 #       existence:platform:kind:algorithms
  18 #
  19 # - "existence" can be "EXIST" or "NOEXIST" depending on if the symbol is
  20 #   found somewhere in the source,
  21 # - "platforms" is empty if it exists on all platforms, otherwise it contains
  22 #   comma-separated list of the platform, just as they are if the symbol exists
  23 #   for those platforms, or prepended with a "!" if not.  This helps resolve
  24 #   symbol name variants for platforms where the names are too long for the
  25 #   compiler or linker, or if the systems is case insensitive and there is a
  26 #   clash, or the symbol is implemented differently (see
  27 #   EXPORT_VAR_AS_FUNCTION).  This script assumes renaming of symbols is found
  28 #   in the file crypto/symhacks.h.
  29 #   The semantics for the platforms is that every item is checked against the
  30 #   environment.  For the negative items ("!FOO"), if any of them is false
  31 #   (i.e. "FOO" is true) in the environment, the corresponding symbol can't be
  32 #   used.  For the positive itms, if all of them are false in the environment,
  33 #   the corresponding symbol can't be used.  Any combination of positive and
  34 #   negative items are possible, and of course leave room for some redundancy.
  35 # - "kind" is "FUNCTION" or "VARIABLE".  The meaning of that is obvious.
  36 # - "algorithms" is a comma-separated list of algorithm names.  This helps
  37 #   exclude symbols that are part of an algorithm that some user wants to
  38 #   exclude.
